Get constants of undefined types in IR
Hi Tim, My mistake not including the llvm-dev, excuse me. affinityElement.__bits[0] worked fine for me, thank you. I am new in using the API for Constants and I am facing the error "incomplete type is not allowed" on the last last of below code: Type * ET = IntegerType::getInt64Ty(I.getContext()); unsigned long size = cpuAffinityVector.size(); ArrayType * AT = ArrayType::get(ET,size);

Build problems
Hello, Could someone please tell me why LLVM and clang downloaded from here: svn co http://llvm.org/svn/llvm-project/llvm/trunk llvmsvn co http://llvm.org/svn/llvm-project/cfe/trunk clang and generated using cmake: cmake -G "Visual Studio 15 2017" ../llvm does not compile in Visual Studio?

Thank you. So the ABI in llvm will be "gnu" for all Linux distributions?

How to debug passes
Iulia, You need to check the contents of the hello.ll (or hello.bc) file rather than the input *.c file - ultimately that's what opt consumes. Try compiling without any optimisations: clang -O0 -emit-llvm -S hello.c -c -o hello.ll -Andrzej On 18/09/2019 11:34, iulia_s24 wrote: > Hi, > > Actually I copy-pasted step 5 from the article in which I found the > solution, in the text

Question about using multiple functions in a Function pass
Hi all, I would want to know if from the runOnFunction method of a Function pass, other functions in IR, except for the one received as parameter, can be obtained as well, from a call instruction, as follows: Function F = dyn_cast<Function>(callInst); Or do I need a Module pass to work in IR with multiple functions from input source code? If so, it is accepted to have O(n^3) complexity in a

How to debug passes
Hi, Could you please confirm the following steps for debugging a pass? 1. copy your pass into llvm/lib/Transforms/Hello/Hello.cpp 2. name you pass Hello 3. insert debug messages like:     errs() << "Vis­iting func­tion " << F.get­Name(); 4. get LLVM bitcode:    clang -O3 -emit-llvm hello.c -c -o hello.bc5. disassemble the bitcode:     llvm-dis hel­lo.bc 6. run the pass on

I want to cross-compile using clang and I have to specify the following triple: <arch><sub>-<vendor>-<sys>-<abi>I know that sub-architectures ("sub" in the triple) for x86_64 Intel Xeon processors could be v2 for ivy bridge or v3 for haswell or v4 etc. Could you please answer: which version of sub-architecture is considered sandy bridge for Intel® Xeon®

LLVM and parallelization
Hi, I know LLVM provides thread-level automatic parallel support using OpenMP (see  http://blog.llvm.org/2015/05/openmp-support_22.html), but it is not clear for me which of the following is correct? 1. Clang inserts in the source code OpenMP compiler directives, so, it auto-parallelizes the serial source code provided as input or2. Clang can compile manually written parallel source code that uses

Question
Hello, 1. Can you please tell me how can I find the type of my Intel Xeon?I see in LLVM code that Intel Xeon processors can be of type "core2", "penryn", "westmere", "skylake". 2. I also see that "skylake" can be a type and a subtype as well.How can I find out the subtype of my architecture? Looking forward for you answer. Thank you.Iulia On

LLVM and Pthreads
Hello, I know clang supports -pthread option (here). Does this mean I can call pthread routines inside llvm code and which pthread library is used, the one for Linux OS or the one for Windows?

[LLVMdev] set of integers to metadata
Hello everyone, I want to pass a set of integers using metadata but I don't know how. I have tried: the integers are in array[] *1. * LLVMContext& C = is->getContext(); Value* values[size]; for(int gy=0;gy<size;gy++){ values[gy]=ConstantInt::getSigned(Type::getInt64Ty(C),array[gy]); } *is->setMetadata("path",MDNode::get(C,values));* failes when setMetadata(),

JIT compiler and calls to existing functions
That seems to work, thanks! The specific code I ended up with to call int64_t print(int64_t) looks like: auto f = builder.CreateIntToPtr( ConstantInt::get(builder.getInt64Ty(), uintptr_t(print)), PointerType::getUnqual(FunctionType::get( builder.getInt64Ty(), {builder.getInt64Ty()}, false))); return builder.CreateCall(f, args); On Mon, Mar

Build error
Hello, I am building LLVM with ninja on Linux environment and I continue to have the error below. I am thinking that the cause might be my PC not having sufficient RAM memory. In this sense, I extended my swap memory with a swap file (90GB), but it didn't solved the problem. Should I add more physical RAM memory to my PC, or is there any software based solution I can try first? Thank you and
